Abstract This research measured the impact of crime prevention through environmental design(CPTED) projects based on crime occurrence data by location. Also this research analyzed the crime displacement and diffusion of benefits due to the project. Five areas were selected for alayzing the CPTED projects, and statistics on crime occurrence were established for each type of administrative dong, district, and Seoul Metropolitan area. The number of crimes were analyzed using descriptive statistics, t-test, and shift-share model. According to the analysis, the CPTED project has been proven to reduce theft crimes by 10% to 60%, and it is more effective in diffusion of benefits than displacement effect of crime caused by the project.
